gpio: merrifield: Move hardware initialization to callback

The driver wants to initialize related registers before IRQ chip will be added.
That's why move it to a corresponding callback. It also fixes the NULL pointer
dereference.

Fixes: 130780a50931 ("gpio: merrifield: Pass irqchip when adding gpiochip")
